Phytochemical Sulforaphane (Dithiolthiones) and Breast cancer

Dithiolthiones are phytochemicals in the class of Organosulfides, found abundantly in cruciferous vegetables, garden sorrel, horseradish, etc.

Breast cancer (malignant breast neoplasm) is a cancer started in the tissues of the breast either from the inner lining of milk ducts (Ductal carcinoma) or the lobules (Lobular carcinoma) that supply the ducts with milk. There is also rare cases that breast cancer starts in other areas of the breast. In 2010, over 250,000 new cases of breast cancer were expected to be diagnosed in women in the U.S. alone and the risk of getting invasive breast cancer during life time of a women is 1/8.

The University of Michigan, insisted that ingestion of sulforaphane at a dose of 50 mg/kg  for 2 weeks inhibited breast cancer stem cells(1). According to Manipal University, Sulforaphane inhibited growth of human breast cancer cell line MCF-7 cells, through induces apoptosis and anti-inflammatory effects on MCF-7 cells via downregulation of Bcl-2 (anti-apoptotic protein) and COX-2 (involved inflammatory process) respectively(2). Also in testing of MCF-7 breast cancer cells, researchers at the The Catholic University of Korea, showed that sulforaphane induced the inhibition of 12-O-tetradecanoyl phorbol-13-acetate (TPA)-induced MMP-9 expression(involved in keratinocyte migration and granulation tissue remodeling during wound healing) and cell invasion via the suppression of the NF-κB (involved in cellular responses)pathway in MCF-7 cells(3).
